An apparatus as disclosed in the illustrative embodiment comprisesgenerally, although not specifically, the following: Amaterial-receiving body is in the form of a trailer body pulled by atractor7 although it may be the truck body itself. This body has anupper entrance for the material at the loading end of the body and hasan outlet at the other end provided with a closure A material-receivingcontainer has a closure, together with means for mounting thecontainerfor movement from a lowered receiving position to an elevateddischarging position over the entrance, and means is provided for somoving the container, adapted to automatically open the clotctt sure anddischarge the material from the container when the container reachessuch elevated position. A packer is mounted at the bottom of the bodyand is movable from below the entrance, forwardly to the other end ofthe body. A stripper in the form of a wall extends downwardly from thetop of the body, forwardly of the entrance and to nearly the top of thetravel of the packer, and this stripper is arranged to strip thematerial from the packer as it recedes rearwardly beyond the stripper. Avalve is positioned above the packer and this valve is movablealternately clear of the entrance to permit the material to bedischarged in front of the packer and across the entrance to nearh thetop of the packer. The stripper, vve and packer are operated incooperative relation. The packer is moved forward and back, beingmovable forward to the wall or stripper, and back for another charge.After the body has been loaded to capacity, the packer is moved forwardafter the front cover has been opened, and is then returned to theloading end of the body. During this movement to discharge the material,the packer is moved forward in successive stages. Suitable mechanism,which may be either hydrauiic or pneumatic, is provided for moving thevarious parts and these are subject to control by the operator.

Referring now to FIGS. l, 2 and 11, a body 1, which in this case is inthe form of a trailer body, is mounted on wheels 2 and 3, the front axleis connected by a drawbar @i to a suitable tractor generally shown at 5.The top of the body is closed as `shown at 6 to the rear loading endwhere an opening is left to provide an entrance at 7 for the material.The front of the body is provided with a closure 8 which is pivoted at 9and which is secured by a hasp It) on the body taking over a perforatedlug 11 on the closure, the hasp and lug being perforated to receive apin 12.

Referring now to FIGS. l, 2 and 3 6, mounted on uprights 13 of channelsection are bearing brackets 14 in which are mounted a shaft 15 carryingtubular extensions 13 additionally braced by brackets 19 to which theextensions 18 are xed, the rwhole being fixed to the shaft 15 to movetherewith. The shaft 15 has a plunger 16 moving in a tubular extension17 mounted on a cross shaft 32 to which is attached the bottoms of theplungers 21 sliding in the tubular extensions 18, 18.

A support 20 is pivoted to the shaft 32. l'fhe support 2i? is arrangedto receive a container 22 having wheels 23, so that it may be moved tothe right away from and towards the body 1, and the support takesbetween the wheels so as to support the bottom 'of the container asshown in FIGS. l and 6. This container has a closure 24 pivoted at 25.The support Ztl has lugs 26 spaced crosswise thereof and beveled at thetop as shown at 27. A cylinder 46 is fixed to shaft 15 and has fluidconnections, `FIG. 13. The cylinder has a plunger 47 attached to theshaft 32, FIG. 3. The cylinder 46 has a lug 28 arranged to be engaged bythe top of the closure 24 of the container 22 so as to hold the topclosure 24 closed.

The container has a bail 29, FIG. 6, which is arranged to receive anopen hook 30 connected to a cable 31 passing underneath the shaft 32between the support 20 and the plungers 21. This cable is connected tothe rod 33 of a piston (not shown) working in a cylinder 34 mounted onthe middle tubular extension 17 shown dotted, FIG. 3, full FIG. 1, andprovided with inlet and outlet fluid connections as shown in FIG. 13. Alug 20a on the left end of the support 20, FIG. 1, is pivotallyconnected with a rod 35 not shown in FIG. 6, and having a piston (notshown) `working in the cylinder 36, provided with inlet and outlet fluidconnections, FIG. 13, and pivoted to a lug 37, FIG. 1, also on themiddle tubular extension 17, FIG. 3.

Referring particularly to FIGS. 1, 3 and 5, the shaft has xed'thereon asheave 38 provided with a V-groove of the type usually employed in ropegearing and around which passes an endless cable 39 passing over idlers40, 41 and 42, FIG. 1. The cable has a clamp 43, FIG. l, connected withthe rod 44 of a piston (not shown) traveling in a cylinder 45 on the topof the body and having uid connections as shown. Referring to FIG. 3, acylinder y46 mounted on the shaft 15 and provided with inlet and outletfluid connections FIG. 13, has a piston (not shown) connected to a rod47, Ain turn connected with the shaft 32.

The operation of the parts thus shown is brieily as follows, amorecomplete rsum of operations being given after a description of thecontrols illustrated in FIG. 13: With the support in lowered receivingposition as shown in FIGS. l and 6, and which may be a few inches abovethe ground, this support is arranged to receive the container 22. Thiscontainer can be taken otI of the support and moved around to receivethe material, the top closure 24 being, of course, at this time opened.With the container iilled, the top is closed and the container is movedover onto the support 2t) which, as previously described, passes betweenthe rolls or wheels 23. The hook 30 is now attached to the bail 29 landthe cylinder 34 is energized, pulling the container 22 to the left, FIG.6, against the lugs 26. The cylinder 36, FIG. l, is now energized toswing the container counterclockwise on shaft 32 against the carrier,i.e. extensions 17, 18 and cylinder 46, with the top 24 of the containerunder the lug 28 on the cylinder 46 so as to hold the top closure downon the container 22, see dotted portions, FIG. 5. The cylinder 45, FIG.1, is now energized operating through piston rod 44 and cable 39connected to sheave 38 on the shaft 15, causing the support 20 and itscontainer to move from lower position to its upper position over the topentrance 7 opening in the body, in the manner shown from FIGS. 1 to 5.During the latter part of that movement the cylinder 46, FIG. 3, will beenergized to move the plunger rod 47 upwardly, the rods 21 rising in thetubular extensions 18 and the extension 17 rising on the plunger 16, soas to raise the support 2.0 and the container thereon, which latter atthis time is inverted, FIG. 5. The lug 28 which is on the cylinder 46will not rise with the container, so that the closure 24 will movevertically away from the lug and will now drop against the lug as shownin full lines, FIG. 5, while the container is in inverted position, soas to discharge its contents through the top opening '7 of the body. Atthat time, however, the container is held against downward movement onthe support 20 at the right FIG. 5, by the bail 29 attached to the hook30 on the cable 31 passing underneath the shaft 32 and holding thecontainer against the lug 26, see FIG. 6, while the container 22 isstill held against tipping on the support 2@ because the upper end ofthe closure, FIG. 5, bears against the top of `46 while the end of theclosure bears against the lug y28 on 46. During the upward movement ofthe inverted container 22 by the plunger 47 in the cylinder 46, theupward movement of the plunger 47 in the cylinder 46 will impart rapidupward movement ofthe inverted container 22 so as to effect rapiddownward discharge of the material in the container.

Referring now to FIGS. 1, 2 and 7-11, sliding on the bottom of the bodyis a packer 5t), this packer having rolls 51 moving in guides 52 alongthe bottom of the body. Mounted at the loading end of the body is acylinder 53 provided with inlet and outlet fluid connections FIG. 13,and having a piston (not shown) whosevrod 54 is connected to the front55 of a slide 56 to which is connected a bunter 70 behind the packer 50.Above the slide 56 is a stationary channel 57 in which slides a linkchain 58 connected at its right end to the packer as shown at 59. Thechain 58 is connected with a pair of cables 66 passing over idlers 61,62 and 63 FIG. 2, and also connected with the packer. A pawl 64 pivotedat 69 on the bunter 70 has a head 65 shaped as shown in FIG. 10 to formhooks `66 taking over pins 67 between the links of the chain 58, andmovable to full and dotted positions shown. The pawl 64 in dottedposition holds the packer against the bunter 70 in the position shown inFIG. 7. The packer has a side wing 68 which, in the full position FIG.7, forms `a guard for the pulley or Wheel 38. Upon energizing of thecylinder 53, and with the pawl 64 in dotted position, FIG. l0, and asshown in FIG. 7, the packer 56 will be moved from the solid to dottedpositions FIG. 7, but this operation will be more fully described later.

Referring to FIGS. 1, 5, 7, 8 and 9, mounted at the forward end of thetop entrance 7 is a stationary wall 75 which has pivoted thereon at 76 avalve 77 connected by a rod 78 to a piston (not shown) in a cylinder 79,provided with inlet and outlet fluid connections FIG. 13, and pivoted atS6 on the wall. Upon energizing of the cylinder 79, the valve 70 ismoved to the positions shown in FIGS. 1, 5, 7, 8 and 9.

Referring again to FIGS. l, 5, 7, 8 and 9, the stationary wall 75terminates above the travel of the top of the packer 50 and guides 81 onthe sides of the body are provided for a movable wall or stripper 82which moves up and down in the guides and which, when down, forms acontinuation of the stationary wall '75. The lower end of this stripperis beveled as shown at S3 and is connected by a rod 84 to a piston (notshown) in a cylinder 85 provided with inlet and outlet connections FIG.13. Upon energizing of the cylinder `35, the piston is moved up and downto move the stripper up and down as shown.

As shown in FIGS. 5 and 7, material is discharged into the space betweenthe packer 56 and the movable wall or stripper 82, while the valve v77is positioned vertically against the guides 81. Thereafter the valve 77moves down to horizontal position, as shown in dotted position FIG. 7,so as to compact the material downwardly. Thereafter the stripper 82 israised as shown in FIGS. 8 and 9, while the valve 77 is still inhorizontal position, and the packer 56 moves to the left to move thecompacted material into the body. The cycle is then repeated.

The mechanism as above described may be operated in any suitable manner;however, FIG. 13 is a diagram showing means for controlling the variouscylinders hydraulically or pneumatically. For this purpose a suitablepump, which may be a rotary or gear pump (not shown), is mounted uponthe tractor and is operated from the tractor motor or engine. Suitablecontrols are mounted on the end of the body, one of such controls beingdiagrammatically shown in FIGS. 3 and 4 at 91). Pressure and returnfluid connections from the iluid pressure pump on the engine extend tothe various controls and from these controls in turn extend connectionsto the various cylinders hereinafter described.

FIG. 13 shows in diagrammatical form a series of controls to the variouscylinders, also diagrammatically shown, and these cylinders areindicated by the same reference numerals as in the other figures; and,for convenience, the control valve for any given cylinder is indicatedby the same reference numeral with 0 added, except that for the jointcontrol of cylinders 53, 79 and 85, the control valve is indicated at579, and the control levers are shown at 90, 91, 92, 93 and 94.Furthermore, for convenience the ends of the cylinders are given thereference numerals L and R which are also applied to the connections tothe controls at L and R. The supply of fluid under pressure to thecontrol valves is indicated at A and the returns are indicated at X, inFIGS. 13, 14 and 1S. The control valves may be of any suitableconstruction, but for illustrative purposes these control valves are inthe form of casings provided with spool valves of well-knownconstruction In the illustrated embodiment, all of the cylinders, eX-cept 53, 79 and 85, are each provided with a control valve asillustrated in FIG. 14 which, for illustrative purposes, is applied tothe cylinder 34. A casing 3401 has movable therein a spool valve S7provided with annular recesses as shown and provided as usual withpacking rings (not shown) between the recesses. This spool valve isconnected by a stern 88 with an operating handle 90 whereby the valvemay be shifted. The ports to this casing are indicated at L, R, A, X andX. In the normal position of the spool valve as shown in FIG. 14, the Land R ports are connected to the L and R ends of the cylinder 34, with Lconnected to the pressure side A of the iluid and with the R portconnected tothe return X of thel iluid, so that the piston in 34 will bein down position. Upon shifting of the valve 87 to the left, FIG. 14,the port R will be connected to the pressure side A of the iluid and theport L to the return side X of the fluid, so that the piston in thecylinder 34 will be moved up to pull the container 24 onto the support201 as previously described.

Spool valves like those shovm in FIG. 14 and provided with operatinghandles designated 91, 92 and 93, are connected to supply the othercylinders 36, 46 and `45 respectively so as to energize those cylindersin the same manner as described in connection with the cylinder 34.

The cylinders 53, 79 and 85 are controlled by a sequence valve 579, FIG.13, with an operating handle 94, and 579 may be in one piece, but, forconvenience, is shown diagrammatically as separated in FIG. 15. Theright part of the valve is like `that shown in FIG. 14, so that thepar-ts :are similarly designated, the spool valve being indicated at870. In this case the L Aand R ports extend to the cylinders 85 and 79,so that upon operation of the -spool valve in a like manner as describedyfor FIG. 14, both of those cylinders will be energized to shift theparts 82 and 77. It will be note-d that the R kand L connections to 85and 79 are in reverse relation so that when uid is supplied thereto thestripper 82 will be down while valve 77 will be up and vice versa, aswill be seen from FIGS. 1, 5, 7 and 8. The R port, however, has anextension 940 which is throttled at 95 :and extends to the right of lacasing 579, FIG. 15, which is provided with a spool valve 871 like thatof valve 87. This spool valve, however, is normally held in rightposition by la spring 96 which may be set at `any suit-able tension by ascrew 97. The ports L and R extend to the L and R ports of the cylinder53 for the packer 50. The purpose of this construction is to secure adelayed movement of the piston in the cylinder 53.

With the controls in .the position shown in FIGS. 13 and 15, the packer50, the valve 77, and the stripper 82 will be in the position shown inFIGS. 5 and 7, that is, with the packer 50 retracted to the right at theloading end, the valve 77 up, and with the stripper 82 down. At thistime the material will be loaded lfrom the Acontainer by operation ofhandles 9i), 91 and 92 and will tall between Si) Iand 82, FIG. 5. Assoon as the container has been moved from elevating to lowered position,by shifting lever 92 the control 94 can be operated to shift the rightspool valve 879, FIG. 14, to the left. That will immediately apply thefull force of the fluid to cylinders 79 and 85 so 4as to move the valve77 down to preliminarily pack the material rin front of the packer.Thereafter the stripper 82 will be raised out of the path of the packeras :shown in FIGS. 1, 8 and 9. The liluid pressure will not be Iappliedto the left valve 871, FIG. 15, supplying cylinder 53 for the packer 50,until the pressure has risen sulciently in the connection 940 toovercome the tension of the spring 96, which iluid pressure is throttledby the reduced opening 9S. This will give a delayed period for theoperation oi the packer, sufficient to permit the valve 77 to drop kandto raise the stripper 82 out of the path of the packer 50, FIGS. 1, 8and 9. The left valve 871, FIG. 15, is then shifted automatically so Iasto cause pressure to be applied to the cylinder 53 so las to move thepacker to the left, FIGS. 1 and 8, underneath and to the left of theWall 75 and the raised stripper 82. Upon now reversing the movement ofthe spool valve 870 by the handle 94 so as .to move it to the right,FIG. 15, so as to operate the packer Si), the stripper 82 and the valve77 in the reverse way than before. `In order to ensure that the packer50 will return to its right loading position FIG. 1 While the stripper82 is still up, a hand valve 98 may be opened, thereby relieving thepressure on the right end of valve 871, FIG. 15, so as to cause itsspring to shift the valve to the right land supply fluid to the left endL of cylinder 53, FIGS. 1 and 14, and return the packer, and valve 99may then be closed. Handle 94, FIG. 15, may now be operated to shift thevalve 870 to supply lluid -to the L ends of cylinders and 79, FIG. 14,in order to move stripper 812 .do-wn and valve 77 up as in full linesFIGS. 5 land 7 to again receive the material. Hand valve 99` may also beprovided to control the operation 'of valve 870 FIG. 15

A rsum of the operation is as lfollows, referring particularly to FIGS.13, 114 and 15 in connection with FIGS. l, 5, 7, 8 and 9. The container22 is taken to a place where it can be loaded, and when loaded, the top`closure 24 is closed and the container rolled over the support 20. Thehook 30` is then att-ached to the bail 29. The operator then actuatesthe controls in the following order: Operation of control pulls thecontainer onto the support 20 and `against the stop 26. Control 91 isthen operated to bring the container against extensions 17 land I18,with the top closure against the lug 28 so as to hold the top closure 24closed. Control 93 is then operated to swing the container upwardlyabout the shaft 15 fand then in inverted condition over the opening 7.Control 92 is the-n operated to further rapidly raise the invertedcontainer and Ito cause the top closure 24 to be released from the lug28 and to drop so las :to rapidly discharge the material in front of thepacker 50` and in back of the stripper 82 which is now down. Control 92is then moved back so yas to drop the container and then control 93 isoperated to swing the tubular extensions 17 and 18 land with them thecontainer back to the position las shown in the lowest dotted position,FIG. 5. During such movements of the part, FIG. 5 full lines, throughthe dotted positions, the lug 28 will again engage the top closure 24 tohold it on the container. Control 91, FIG. 13, is now operated to swingthe support 20 and its container 22 about the pivot 32 from the lowerdotted position, FIG. 5, to full positions, FIGS. 1 and 6, causing thetop of the container to move free of the lug 28 and to release the topclosure 24. Control 90 is now operated to permit release of the bail 29from the hook 30 thereby allowing the container to be moved lfree of thesupport 20 for refilling. The operator will now, or while controls 92,93, 91 fand y90 are operated, :actuate control 94 so las to rst move thevalve 77 down to preliminarily pack the loose material in front of :thepacker while the stripper 82 is raised. After a `delayed yaction due tothe restriction 95, the packer 50 moves Iforwardly to push the materialthrough the opening below the wall 7S and into the body. The valve 98 isthen moved back so as to cause the packer 50 to move back to loadingposition, `after which the handle 94, FIG. 14, is moved to move thestripper down while the valve 77 moves up, as shown in FIGS. 5 and 7.This operation is successively repeated so as to successively loadmaterial in front of the packer and to successively load the materialinto the body until the body has been lilled. By the operation ofcontrol 94 the packer 50 and the valve 77 `and the stripper 82 are movedin synchronism but Without interference. There is no liability of thematerial falling back into the space below the stripper because thestripper is moved down in back of the material.

After the body has been lled, the contents of the body are ejected inthe Ifollowing manner: The cover or closure `8 is unliatohed and movedup. The packer is then moved forwardly in successive steps. In order toaccomplish this and render the operation of the valve and stripperinactive, manually operated valves 98 and 99 are provided -as shown inFIG. 15, so that upon operation of the control `94, :and after thestripper S2 is raised, there will be no supply of iluid to the cylinders79 and 85, but only to the valve 87,1 and the cylinder 53 of the packer.The packer is now moved forward by operationcf the control 94 at whichtime, as just noted, the valve and shipper remain inactive. With thepacker in forward position, the pawl 64 is moved from dotted position,FIG. 10, to full position. Upon return movement lof the control 94 and-as the slide 56 returns, carrying the bunter 70` with it, the pawl-will -slide over the pins 67 of the chain 58, leaving the packer int-he position shown in dotted lines, FIG. 7. Upon again operati-ng thecontrol 94, the packer 50 is moved forward an additional step; this stepis repeated until the packer moves to the extreme forward end of thebody as shown in dotted lines at the left, FIG. l, so as to push thecompacted material out ofthe body. This material will have beencompacted sufficiently from top to bottom so that none of the materialWill slough over the top of the packer.

In order .to now return the packer to its` loading position, the pawl 64is moved from lfull to dotted position, FIG. 10. Upon operation of thecontrol 94, at which time the valve 99 is closed so as to keep thestripper 82 up and the valve 77 down, the packer is shifted back toLoading position in successive stages until it finally arrives at theposition at the loading end of the body and with the packer :against thebunter 70.

FIG. 12 shows another embodiment of this invention. Here the parts havebeen given the same reference numerfals as in the other figures, exceptthat the cylinder numbered 530 is longer. The slide 56 is in this caseprovided with a bunter 102 which is arranged -to take against a lug 100on the packer 50 and a removable pin 101 passing through the sides yofthe slide engages the left end of the lug 100. When the parts are asshown at the right, and with the valves 98 and 99 closed, energizing ofthe cylinder 530' will move the packer forward Vfrom full tointermediate dotted position. The pin 161 is then removed so that Iuponreversal of the piston in the cylinder 530, the packer 50 will be leftin 4the intermediate position. The pins 103 and 164 are now placed onopposite sides of the lug 160' as shown in the middle of the figure.Upon again energizing of the cylinder 530, the packer will now be movedto another position shown at the extereme left of FIG. 12. There may bea number of successive stages of movement of the packer, depending uponthe length of the cylinder 530. In the nal position, when the packer isat the right end of the body and the cover 8 having been opened, thepacked material will be pushed out. In order to return the packer, themovement from the left to the middle position by reversal of the pistonin the cylinder is accomplished without taking out the pins 103 and 104;thereupon the pins 103y and 104 are removed upon then again moving thepiston to the left until the bunter 102 engages the lug X100; then thepin tltil is replaced so that upon moving the piston to the right thepacker will be brought back to the position at the right.

It will therefore be seen that this inventionV accomplishes its objects.An apparatus is provided by which the collection of materials isfacilitated,in which the material can be temporarily stored in a bodysuch as a trailer or truck body and compacted therein, and which canthen be moved to a suitable location and the materials discharged.
